Live blogging conferences: Physics!

May 23, 2008

Our Italian friend at A Quantum Diaries Survivor is in Albuquerque for PPC08 — don’t ask me what that stands for, but it’s a physics conference.  More, he found another physicist blogging away:  World o Science.

If you’re interested in science research, check it out.  Some of the posts are terribly technical — I don’t understand them, so I’ll have to get one of our sons to explain it to me — but you can catch the drift of what’s going on.  Tommaso also offers a few photos of the Albuquerque area and Sandia Peak, worth the click alone.

It’s a good model of what some of us should do more of (yeah, this is self-flagellation).

Science funding: Kicking our future away

April 9, 2008

Drat.

We get Charlie Rose’s program late here — generally after midnight. I’m up to my ears with charitable organization duties (“Just Say No!”), work where I came in midstream, family health issues, and other typical aggravations of trying live a well-examined life.

I caught most of an hour discussion on science in America, featuring Sir Paul Nurse, president of Rockefeller University and Nobel laureate, Bruce Alberts, editor of Science, Shirley Ann Jackson, president of  Rensselaer Polytechnic Institute, Harold Varmus, Nobel winner and president of Memorial Sloan-Kettering Cancer Center, and Lisa Randall, the Harvard nuclear physicist (string theory).

It was a great policy discussion. It had great humor, and great wisdom. And at the end, Rose thanked Nurse and others for helping him put on a 13-part seminar on science policy.

Thirteen parts? And I caught just the last few minutes of #13?

There is the Charlie Rose archives! Here’s the show I caught, “The Imperative of Science.” Great discussion. Scary — Lisa Randall notes that the action in physics has moved to CERN, in Europe, and the search for the Higgs Boson. Varmus and Nurse talk about restrictions in funding that bite at our ability to keep the world lead in education and science. Educators, especially in science, should watch.

Are we kicking away our ability to lead in technology, health care, and other vital economic areas? One cannot help but wonder in listening to these people discuss the difficulty of getting support for critical research during the Bush administration. They each stressed the hope that the next president will be one literate in science.

Pfizer underwrote the series. The entire series is available for viewing at a site Pfizer set up(Signs of change:  Notice that physics is represented by two women; there are signs of hope in American science.)

Go see, from Pfizer’s website on the series:

NASA needs eyewitnesses: Were you at the intersection of Milky Way and Bootës on the evening of March 19?

March 21, 2008

No kidding. Our Italian physicist friend Dorigo passed along the note on his blog, Quantum Diaries Survivor. George Gliba at NASA (gliba@milkyway.gsfc.nasa.gov) hopes someone was watching Bootës at about 6:10 UT (which would be about 1:10 a.m. Central Daylight Time (CDT), if I’m calculating that correctly).

Gliba said:

Last night the NASA SWIFT spacecraft saw the most extrinsically luminous Gamma-ray Burst ever known. Some ground based telescopes recorded the visual optical afterglow to be 5th magnitude!

Here’s your chance to make science history: If you may have seen the thing, or better, if you have a videotape of the incident (which may have lasted a few minutes), scientists would sure love to see it.

Here’s what the Swift telescope captured:

Gamma Ray burst in Bootes, GRB 080319B
The extremely luminous afterglow of GRB 080319B was imaged by Swift’s X-ray Telescope (left) and Optical/Ultraviolet Telescope (right). This was by far the brightest gamma-ray burst afterglow ever seen. Credit: NASA/Swift/Stefan Immler, et al.

So, did you see it? Call George Gliba; details, Gliba’s note to physicists and astronomers below the fold.

What is a gamma ray burst?

Most gamma ray bursts occur when massive stars run out of nuclear fuel. Their cores collapse to form black holes or neutron stars, releasing an intense burst of high-energy gamma rays and ejecting particle jets that rip through space at nearly the speed of light like turbocharged cosmic blowtorches. When the jets plow into surrounding interstellar clouds, they heat the gas, often generating bright afterglows. Gamma ray bursts are the most luminous explosions in the universe since the big bang.

“This burst was a whopper,” said Swift principal investigator Neil Gehrels of NASA’s Goddard Space Flight Center in Greenbelt, Md. “It blows away every gamma ray burst we’ve seen so far.”

Calculations show this one was 7 billion light years away. Cool!

Feynman: The beat goes on

March 11, 2008

Wow.

I believe this is an excerpt from a NOVA tribute to Feynman, which has never been available commercially so far as I have found.  Anybody know how to get a copy of the video?

Among other things, the piece included comments from some of Feynman’s closest friends, and it detailed their fascination with a tiny republic then inside of the Soviet Union, Tannu Tuva, which Feynman had determined to be the most obscure and difficult nation on Earth to travel to — and so, of course, he wanted to go.  The place is known today as Tuva.

No denying the man his orange juice.


Quote of the moment: Richard Feynman, science vs. public relations

January 7, 2008

Feynman speaking from the grave? You decide:

Feynman uses a glass of ice water to show the Challenger's O-ring problem, 1986

For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

    December 30, 1924, Hubble Day: Bigger universe than you can imagine

    December 30, 2007

    Edwin Hubble

    December 30, 1924, Edwin Hubble announced the results of his observations of distant objects in space.

    In 1924, he announced the discovery of a Cepheid, or variable star, in the Andromeda Nebulae. Since the work of Henrietta Leavitt had made it possible to calculate the distance to Cepheids, he calculated that this Cepheid was much further away than anyone had thought and that therefore the nebulae was not a gaseous cloud inside our galaxy, like so many nebulae, but in fact, a galaxy of stars just like the Milky Way. Only much further away. Until now, people believed that the only thing existing outside the Milky Way were the Magellanic Clouds. The Universe was much bigger than had been previously presumed.

    Later Hubble noted that the universe demonstrates a “red-shift phenomenon.” The universe is expanding. This led to the idea of an initial expansion event, and the theory eventually known as Big Bang.

    Hubble’s life offered several surprises, and firsts:

    Hubble was a tall, elegant, athletic, man who at age 30 had an undergraduate degree in astronomy and mathematics, a legal degree as a Rhodes scholar, followed by a PhD in astronomy. He was an attorney in Kentucky (joined its bar in 1913), and had served in WWI, rising to the rank of major. He was bored with law and decided to go back to his studies in astronomy.

    In 1919 he began to work at Mt. Wilson Observatory in California, where he would work for the rest of his life. . . .
    Hubble wanted to classify the galaxies according to their content, distance, shape, and brightness patterns, and in his observations he made another momentous discovery: By observing redshifts in the light wavelengths emitted by the galaxies, he saw that galaxies were moving away from each other at a rate constant to the distance between them (Hubble’s Law). The further away they were, the faster they receded. This led to the calculation of the point where the expansion began, and confirmation of the big bang theory. Hubble calculated it to be about 2 billion years ago, but more recent estimates have revised that to 20 billion years ago.

    An active anti-fascist, Hubble wanted to joined the armed forces again during World War II, but was convinced he could contribute more as a scientist on the homefront. When the 200-inch telescope was completed on Mt. Palomar, Hubble was given the honor of first use. He died in 1953.

    “Equipped with his five senses, man explores the universe around him and calls the adventure Science.”

    That news on December 30, 1924, didn’t make the first page of the New York Times. The Times carried a small note on February 25, 1925, that Hubble won a $1,000 prize from the American Academy for the Advancement of Science.

    Update, December 31: CBS’s Sunday Morning has an “Almanac” feature weekly; Hubble was featured on December 30. Unfortunately CBS has not posted the video. However, I did find a description of Hubble’s work on YouTube — in true, irritating internet fashion, stripped of citations. The video is below. If you know details — who made the video, where good copies might be available — please note it in comments.

    Update:  See the 2009, improved  Hubble Day post here.

    Quote of the moment: Newton, giants

    December 26, 2007

    Newton, by Sir Godfrey Kneller, 1689

    If I have seen further than others, it is because I have stood on the shoulders of giants.*

    Sir Isaac Newton (1642-1727), letter to Robert Hooke, February 5, 1675/1676. Newton was born on December 25 by the Julian Calendar, at a time when it mattered which calendar was used.


    [*] Newton’s giants: Nicolaus Copernicus, Giordano Bruno, Johannes Kepler, René Descartes. Bartlett’s 16th Edition phrases the letter to Hooke a little differently: “If I have seen further than (you and Descartes) it is by standing upon the shoulders of Giants.” Others attribute the quote much earlier; it was a saying of the times, it appears, and this is one of the most famous uses of it.


    Physics under fire: Fermilab budget cuts

    December 22, 2007

    Remember the State of the Union pledge to put science front and center in building the nation’s economy?

    That was then, this is now: Fermilab is cutting projects due to reduced federal funding. The U.S. is ceding pre-eminence in particle physics to CERN in Europe, or anyone else who will simply spend the money.

    Dorigo has the details and links, at A Quantum Diaries Survivor.

    It is clear that the US congress does not believe pure research in subatomic physics something useful for the Nation. Let’s face it: we lived through sixty years of good funding on the standing wave of nuclear weapons research, but we do not seem to manage to fool anybody anymore: no more deadly tools from muons and neutrinos. So, no dough. Sad, but true. I only hope that Europe will be smarter and that particle research at CERN will continue as strong as it has been recently shown to be.

    Regret to start your weekend on down notes; science does best if syncopation is not limited, however. Get out there and play.


    Bending science to keep religion rigid

    December 17, 2007

    Texas A&M University will be home to an institute to train students for careers in nuclear power. This is a logical and welcome extension for one of Texas’s, and one of the nation’s premiere engineering schools. Nuclear power offers opportunities for the nation made more urgent by continuing, inherent problems with carbon-based fossil fuels.

    Radioactivity symbol

    Texas is the nation’s second largest state. The institute will provide another source for Texas kids to get career training.

    The Nuclear Power Institute will help train staff needed to operate new reactors and generating plants. It will also revamp curriculum for junior high, high school and college students who are interested in pursuing careers in the field, according to officials with Texas A&M Engineering.

    The institute was established in a joint effort by the Dwight Look College of Engineering and the Texas Engineering Experiment Station (TEES). The Look College is one of the largest engineering colleges in the nation, with nearly 9,000 students and 12 departments.

    “The Texas A&M University System is uniquely configured with the ideal combination of education, research and service agencies and universities to lead this effort,” Vice Chancellor and Dean of Engineering Kem Bennett said in a statement released last week. “The institute will make a significant impact upon the work force and economy of the state and nation.”

    The Texas A&M University System Board of Regents signed off on the formal creation of the Nuclear Power Institute earlier this month.

    There is a high degree of irony in this announcement at this time. While Texas A&M looks to the future with nuclear power, the state weighs whether to allow a Dallas religious school to train teachers that management of nuclear power is based on flawed theory. A&M will train people to manage nuclear power; the Institute for Creation Research (ICR) wants to train high school teachers to teach Texas’s high school kids that nuclear power is mysterious and cannot work.

    Does Texas contradict itself? Walt Whitman might have asked. Texas is large. It contains multitudes.

    But should it contain a school that teaches much of basic science is just wrong?

    It might be nice if a higher percentage of the multitudes had the reasoning power to see what’s wrong with this picture, and why the question is important.

    This may be too subtle for people unfamiliar with atomic theory to realize the full impact. Zeno at Halfway There explains the wacky part of ICR’s misunderstanding, or wishful thinking about atomic theory. Simply put, ICR claims to have discovered that God interferes with nuclear reactions, making it difficult to predict that a nuclear reactor won’t suddenly increase its output by ten times, cooking the nuclear power plant and a couple of nearby towns in the doing.

    Texas A&M is working to prepare people to live in the late 21st and 22nd centuries. ICR is fighting to take us back to the 16th or 17th century.

    If ICR is successful, from what pool will A&M draw its candidates for nuclear engineering and nuclear power management? Against its will, Texas A&M could become one of the largest graduate institutions for all of India and China.

    Please see the update, December 18, here:  Texas’s face should be creationism red.


    Creationism school wants to offer master’s degrees

    December 15, 2007

    If the venerable, old and wrong Institute for Creation Research hoped to sneak through their request to grant graduate science degrees in creationism, they are disappointed this morning. The Dallas Morning News exposed their plans on the front page: “Creation college seeks state’s OK; Dallas school plans master’s in science education, fueling debate over teaching evolution.”

    To be more accurate, the headline should have said “fueling debate over teaching creationism,” since that’s where the controversy lies.

    Also see the story in the Austin American-Statesman. (Update 12/19/2007 — see these posts, too: Lack of resources; Bending science to keep religion rigid.)

    Steve Benson cartoon from 2004, creationists Cartoon by Steve Benson of the Arizona Republic, 2004; via Panda’s Thumb

    It’s scary to think people can be granted a degree in lying to innocent children, and that it would be counted as a factor in favor of their teaching, instead of as a problem to be overcome like a bad background report.

    But ICR was granting degrees in California. They hope to expand their sales in Texas, closer to the Bible Belt’s buckle.

    A state advisory group gave its approval Friday; now the final say rests with the Texas Higher Education Coordinating Board, which will consider the request next month.

    How will the state’s serious higher education institutions respond? What should Texas education officials do? It’s a difficult question, really. Generally states allow any institution that gets accreditation to grant degrees. ICR was denied accreditation in California, but set up a separate accrediting company for Bible colleges and religiously affiliated schools. When the U.S. Department of Education authorized that accrediting association as acceptable for Pell Grant and Stafford Grant purposes, California’s ability to stop the madness was limited. Texas allows degrees for colleges that teach chiropractic medicine, and there are probably several other degree granting programs that would raise eyebrows of rational people, were they better known.

    “It just seems odd to license an organization to offer a degree in science when they’re not teaching science,” Mr. [Dan] Quinn [of the Texas Freedom Network] said.

    “What we’re seeing here is another example of how Texas is becoming the central state in efforts by creationists to undermine science education, especially the teaching of evolution.”

    A group of educators and officials from the state Coordinating Board visited the campus in November and met with faculty members. The group found that the institute offered a standard science education curriculum that would prepare them to take state licensure exams, said Glenda Barron, an associate commissioner of the board.

    Dr. Barron said the program was held to the same standards that any other college would have to meet.

    “The master’s in science education, we see those frequently,” she said. “What’s different – and what’s got everybody’s attention – is the name of the institution.”

    No, it’s not the name of the institution that worries us — it’s their history of defending buncombe, hoaxes and falsehoods as science, detracting from the education of science in a major way.

    Science education in the U.S. is under assault. ICR is asking Texas to surrender the nation’s future and accept the ICR’s white flag of ignorance as the state’s own. It is unclear to me whether the state may refuse to do that, though it would be the moral thing to do to refuse.

    Quote of the moment: Wolfgang Pauli, “not even wrong.”

    December 14, 2007

    Wolfgang Pauli, before 1945 - Nobel Foundation photo
    Photograph of Wolfgang Pauli, circa 1929; photo from Nobel Foundation.

    That’s not right. It’s not even wrong.

    From Wikipedia:

    Wolfgang Pauli (1900-1958), as quoted by R. Peierls

    Peierls (1960) writes of Pauli, “… a friend showed him the paper of a young physicist which he suspected was not of great value but on which he wanted Pauli’s views. Pauli remarked sadly ‘That’s not right. It’s not even wrong'”.  (Peierls  R  (1960). “Wolfgang Ernst Pauli, 1900-1958”. Biographical memoirs of fellows of the Royal Society 5: 174-92. Royal Society (Great Britain))

    Pauli won the Nobel Prize in Physics in 1945:  “At this stage of the development of atomic theory, Wolfgang Pauli made a decisive contribution through his discovery in 1925 of a new law of Nature, the exclusion principle or Pauli principle. The 1945 Nobel Prize in Physics has been awarded to Pauli for this discovery.”


    Paul Davies bucks the trend toward reason in physics – faith instead?

    November 24, 2007

    In 2003 Physics Nobel Winner Steven Weinberg made a stunning presentation to the Texas State Board of Education on why evolution needs to be in biology texts.

    Live by the physicist, die by the physicist: Paul Davies takes it back, giving aid and comfort to the intelligent design/creationist camp, in Saturday’s New York Times. While he doesn’t mention evolution or biology, the Public Spin Department at the Discovery Institute is probably at work on press releases touting Davies’ piece right now.

    Oy.


    Belated: Happy Anniversary, Chuck Yeager!

    October 20, 2007

    Panorama of the Mountains noted the 60th anniversary of the first known faster-than-sound flight by a human — October 14, 1947. Test pilot and all-around good guy Chuck Yeager did it.

    Bell X-1, on display at National Air and Space Museum

    This is a great post-World War II, Cold War story of technology that should pique interest in the time and the events for many students. For a 90 minute class, a solid lesson plan could be developed around the science and technology of the flight (yes, even in history — this is key stuff in the development of economics, too). The physics of sound, a brief history of flight and aircraft, the reasons for post-war development of such technologies, the political situation: There are a dozen hooks to get into the topic. Fair use would cover showing a clip from “The Right Stuff” about the flight, and there are some dramatic clips there. (The movie is 3 hours and 13 minutes; great stuff in a format too long for classroom use. Is there any possibility your kids would read the Tom Wolfe book?)

    When will someone – the Air Force? NASA? an aircraft company? — put together a DVD with authorized film clips from the newsreels and the movie, and suggested warm ups and quiz questions?

    Back in the bad old days one of my elementary school teachers did an entire morning on the speed of sound, aircraft engineering, and the history of faster-than-sound flight. I learned the accurate way to measure the distance to lightning by counting seconds to the thunder (it’s about a mile for every 5 seconds, not a mile for every second, as our school-yard lore had it).

    • Image at right: Brig. Gen. Charles E. Yeager today, with image of Bell X-1; U.S. Air Force imageChuck Yeager, collage with Bell X-1

    This program, to fly at the speed of sound, at what is now Edwards Air Force Base changed the way science of flight is done in the U.S. Yeager led the group of Air Force pilots who proved that military pilots could do the testing of aircraft; the project proved the value of conducting research with experimental aircraft on military time. The methods developed for testing, evaluating, redesigning and retesting are still used today. The drive for safety for the pilots also grew out of these early efforts at supersonic flight.

    Yeager’s flight came when technology was cool, not just for the virtual reality role playing games (RPGs), which were still decades in the future, but because it was new, interesting, and it opened a world of possibilities. We all wanted to fly airplanes, especially small, fast airplanes. Read the rest of this entry »


    2007 Nobel Prizes in Physics – Giant magnetoresistance

    October 9, 2007

    The Nobel Committees are working overtime to frustrate my predictions this year.

    Two Europeans won the Nobel Prize in Physics. Albert Fert, Unité Mixte de Physique CNRS/THALES, Université Paris-Sud, Orsay, France, and Peter Grünberg, Forschungszentrum Jülich, Germany, won for the discovery of “giant magnetoresistance.”

    It’s called one of the first real applications of nanotechnology. Here’s an explanation from IBM’s website, of how the discovery affects new hard drive technologies. This is the basic technology for the working of your hard drive.

    Go see the press release from the Nobel Foundation. Video of the announcement ceremony should be available here, later today.

    Score so far this year: Five awards, one person schooled in the U.S, by Quaker schools, not public schools. My predictions that the awards go to U.S. citizens schooled in the public schools are not doing well, so far this year. Is the trend over already?


    Nobel prizes in the classroom

    October 8, 2007

    One of my elementary teachers used to make a big deal of the Nobel Prizes every year. We’d get the newspaper clips on the prizes, calculate how much they were worth, and discuss what the people did to win them.

    Nobel Prize medallion, from Deccan Herald

    Several years ago I started offering grade boosts to economics students who could predict the winner of the Nobel Memorial Prize in Economics. One year I actually had to pay up, after another teacher discovered a Nobel handicapping site, and one student got very, very lucky. What other uses can you find?

    I especially remember the prize to Penzias and Wilson in Physics in 1978, because it meant we didn’t have to study Steady State any longer (and I’d always found that description confusing). Steady State was still in some books, more than a decade after their discovery of Big Bang.

    Here’s the schedule for Nobel announcements, over the next week or so:

    Announcements of the 2007 Nobel Prizes and The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel will be held on the following dates:
    Physiology or Medicine – Monday, October 8, 11:30 a.m. CET (at the earliest)
    Physics – Tuesday, October 9, 11:45 a.m. CET (at the earliest)
    Chemistry – Wednesday, October 10, 11:45 a.m. CET (at the earliest)
    Literature – Thursday, October 11, 1:00 p.m. CET (at the earliest)
    Peace – Friday, October 12, 11:00 a.m. CET
    Economics – Monday, October 15, 1:00 p.m. CET (at the earliest)

    While working in education policy years back I noticed that Nobel winners come disproportionately from the U.S., and disproportionately from the public schools. Watching such trends tends to be a practice of journals outside the U.S., however, such as the Times of India:

    Americans tend to dominate the science prizes and last year they made a clean sweep, taking the medicine, physics, chemistry and economics awards. Read the rest of this entry »
